Probably nothing special. They used to do search well, now they are into everything, a pretty good indication that the results will be average. Their search certainly changed the web, but what have gmail, google maps, google earth, froogle, google talk, google news changed? I've tried all of them, very excited for a few days/weeks, then back to my old stuff. In other words, they revolutionized the web 5-6 years ago, made lots of money, created lots of cool stuff, but nothing revolutionary since.
